Chemical composition of A-F type post-AGB candidates.

Abstract (from CDS):

An abundance analysis has been conducted for a sample of nine post-asymptotic giant branch (AGB) candidate stars; eight of them have not been explored before. We find four very promising objects like HD105262, HD53300 and CpD-62° 5428 among them. We find strong evidence of dust-gas separation through selective depletion of refractive elements in HD105262. The same effect is also observed in HD53300, CpD-62° 5428 and HD114855 although abundance peculiarities are relatively smaller for the last two stars. We find strong enrichment of nitrogen for HD725, HD842, HD1457, HD9233 and HD61227 but no further evidence to support their post-AGB nature. We have compared the observed [N/C] ratios of these stars with the predictions of evolutionary models which include the rotation-induced mixing.
